Prompt Enhancer: a desktop Promptly alternative that works system-wide
If you’re looking for a Promptly alternative, here’s an honest comparison. Promptly is a Chrome extension. Prompt Enhancer is a native desktop app. They both make your prompts better — but they live in different places and do their work differently. This page lays out the verifiable differences so you can pick the right one.
Both products are called “Promptly” in this space; this comparison refers to the popular Promptly – AI Prompt Enhancer & Manager Chrome extension for ChatGPT, Claude, and Gemini. Pricing and privacy policies change, so always confirm the current details on Promptly’s own Chrome Web Store listing before deciding.
What Promptly is
Promptly is a free browser extension for Chrome. It runs inside web-based AI chats — ChatGPT, Claude, Gemini, and others listed on its store page — and adds three main things:
- One-click prompt optimization. Highlight or type a prompt and press Ctrl+M (Cmd+M on Mac) to rewrite it into a clearer, more structured version, directly in the chat box.
- A prompt library. Save your own prompts, browse a community template library, and insert them with a search palette.
- Conversation export and summary. Export or summarize a chat (Ctrl+E) so you can reuse or share it.
Its Chrome Web Store listing shows an established user base and rating. If you live inside browser AI chats and want a free, lightweight way to clean up prompts and reuse templates, Promptly is a sensible pick. Check its current rating, user count, and privacy disclosures on the listing yourself — those numbers move, so we don’t quote a fixed figure here.
What Prompt Enhancer is
Prompt Enhancer is not a browser extension. It is a small native desktop app (macOS and Windows) that adds a system-wide hotkey.
You write a rough draft anywhere — Cursor, VS Code, Claude Code, a terminal, Notion, Slack, Linear, Mail, or a browser tab. You press ⌃⌥⌘P (macOS) or Ctrl+Alt+P (Windows). In under 4 seconds your selected text is rewritten in place using Anthropic’s official XML prompt structure: <role>, <context>, <task>, <output_format>.
No window switching. No copy-paste. The cursor stays where it was. The result is a prompt Claude actually parses well — not just a tidied-up version of what you typed.
Prompt Enhancer ships with seven purpose-built presets — chat, Claude Code, Codex, image (Nano), image (Midjourney), video, and research — so the structure matches the model you are aiming at. Image and video presets output in English.
The core difference: browser extension vs. system-wide desktop alternative
This is the whole decision in one line:
- Promptly works where the browser works. It is a Chrome extension, so it acts on web pages — primarily the AI chat sites it supports. That is exactly right if your AI work happens in browser tabs.
- Prompt Enhancer works everywhere your keyboard works. Because it is a desktop app with a global hotkey, it rewrites text in any native application — IDEs, terminals, note apps, chat clients — not only the browser.
If you prompt Claude through Cursor, Claude Code, or a terminal, a Chrome extension cannot reach that text. A system-wide hotkey can.
Pricing
Promptly is listed as free on the Chrome Web Store, with premium features described as “coming soon.” Because that can change, confirm the current pricing on its listing before you rely on it.
Prompt Enhancer:
- 3 free enhancements — no signup, no API key, no credit card. Then a 7-day free trial (email, no password).
- Pro BYOK — with a Pro license, bring your own Anthropic API key; traffic goes directly to
api.anthropic.com, the key is stored in the OS keychain, no proxy in between. - Pro Lifetime: $29 one-time. No subscription, no renewal.
When to choose Promptly
- Your AI work happens almost entirely in browser tabs (ChatGPT, Claude, Gemini on the web).
- You want a free tool with a built-in prompt library and conversation export.
- You do not need to structure prompts in desktop apps like Cursor, VS Code, or a terminal.
- You are comfortable installing a Chrome extension that reads page content (review its permissions and privacy disclosures first).
When to choose Prompt Enhancer
- You write prompts outside the browser — in Cursor, VS Code, Claude Code, a terminal, Notion, or Slack.
- You specifically want Anthropic’s XML prompt structure (
<role>/<context>/<task>/<output_format>), not a generic “make it clearer” pass. - You want in-place rewriting via a global hotkey, with the cursor never leaving your draft.
- You prefer a BYOK tool where your prompts go straight to Anthropic with no intermediary server.

| What it is | Native desktop app (menu-bar / system tray) | Chrome browser extension |
| Where it works | Any app, system-wide — IDEs, terminals, note apps, browser | Inside supported web AI chats (browser only) |
| Trigger | Global hotkey: ⌃⌥⌘P (macOS) / Ctrl+Alt+P (Windows) | Ctrl+M / Cmd+M inside the page |
| Core job | Rewrites your draft into Anthropic XML structure in place | One-click prompt optimization + prompt library + chat export |
| Output format | Anthropic XML: <role> <context> <task> <output_format> | Clearer, restructured prompt (format set by Promptly) |
| Prompt library / templates | No (focused single-purpose tool) | Yes — personal + community library |
| Conversation export / summary | No | Yes |
| Models targeted | Anthropic Claude (XML), via 7 task presets | ChatGPT, Claude, Gemini, and others per its listing |
| Pricing | 3 free, no signup, then a 7-day free trial; $29 lifetime Pro | Free on Chrome Web Store (premium features noted as coming soon — verify) |
| Privacy model | BYOK; key in OS keychain; direct to api.anthropic.com, no proxy | Reads page content; review its store privacy disclosures |
| Platform | macOS + Windows; Linux planned Q3 2026 | Any OS that runs Chrome (browser-level) |
| App signed / notarized | macOS: Apple-notarized, opens normally; Windows: unsigned, one-time SmartScreen prompt | Distributed via Chrome Web Store review process |
| Maturity | New (2026 launch), no public review history yet | Established listing with users and ratings (check the live store listing for current figures) |
Honest caveats
- We are newer. Prompt Enhancer launched in 2026 and has no long public track record, no large user base, and no third-party reviews yet. Promptly’s Chrome Web Store listing shows an established user base and rating. If a proven user base matters to you, that is a real point in Promptly’s favor — see its listing for the current numbers.
- Our macOS DMG is Apple-notarized since June 2026 — installs without Gatekeeper warnings. The Windows installer shows a one-time SmartScreen “unknown publisher” prompt while code-signing reputation accumulates.
- Different scope, not a strict upgrade. Promptly does prompt management, a template library, and chat export — Prompt Enhancer does none of those. If you want a prompt library and conversation export inside the browser, Promptly fits better. Prompt Enhancer does exactly one thing: structure a draft into an Anthropic XML prompt, anywhere on your desktop.
- Verify Promptly’s current details yourself. Free status, premium tiers, supported models, ratings, and privacy/data-handling disclosures can change after this page was written. Check Promptly’s own Chrome Web Store listing before deciding — do not take any competitor claim here as a substitute for its live page.
- Browser-only vs. system-wide is the real fork. If all your AI work is in browser tabs, a Chrome extension may be all you need. If you prompt from Cursor, Claude Code, or a terminal, only a desktop hotkey can reach that text.
